Release	Release notes
Yokohama	Yokohama Patch 11 Changes to Now Assist usage measurement Starting with Yokohama Patch 5, Now Assist usage measurement is transitioning from a 365-day look-back model to a 365-day burn-down model, with usage resetting at the contract anniversary date. For more information, refer to KB KB2704710: Now Assist Usage - Overview & New Measurement Logic. Some Now Assist skills, agents, and agentic workflows are turned on by default The skills are automatically available to appropriate role users for the application, such as ITIL roles on incident forms or change forms. This change simply activates the skill and does not touch the roles that may be needed to use the skill. The new default behavior works as follows: New customers: When you install a Now Assist product, designated skills and agentic workflows are turned on automatically. Existing customers who are upgrading (starting with Yokohama Patch 11): Any previously unconfigured skill, agent, or agentic workflow is turned on automatically (the AI asset was never configured and turned on, then turned off again). Previously configured skills and agentic workflows that were turned on, then off, remain inactive. Previous Patch releases More easily identify changes when previewing and updating applications When previewing an application, any requested changes made by the Now Assist for app generation skill are listed when the preview pane loads. Edit applications without having to change the scope manually When editing applications, the Now Assist for app generation skill now changes the scope that you’re working in to the scope of the application automatically. More easily query Analytics Generation Analytics Generation now uses a semantic filter instead of Natural Language Query (NLQ), resulting in less rigid requirements for queries. Yokohama Patch 1 Improved query engine for Analytics Generation Starting in Yokohama Patch 1, analytics generation supports GPT-4o for generating queries, to provide better accuracy in responses. These improvements include support for up to two levels of dot-walking based on user utterances.
